GHALKIIN'G DEVICE FOR BILLIARD-TABLES.

i To all whom it may concern:

Be it known that I,' ZAVERIO ,O. BIANoHI, v a citizenof the United States,,residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Chalking Devices for Billiard-Tables, of which the following is a specification.

My invention relates to improvement in a chalking device for billiard tables, and the objects of my device are:

. First; to provide a chalking device for billiard tables that will prevent the wasting of chalk. p l t I Second; to provide a chalking device that will bring the chalkholder over the billiard table within reach of the hand.

Third; to provide a chalking device that will operate over a plurality of billiard tables inline. r I Fourth; to-prfovide a chalking device that will operate over a plurality of billiard tables, oneechalk holder not interfering with the operation of the other chalk holder.

Fifth; to provide a chalkingdevice that will at all times return thechalk holder to its original position afterthe 'chalkjhas been used.

Otherwbject-s. andadvantageous features 1 pulley hangers of the invention will be fully understood from the following description and claims when the same are read in connection with holder with chalk the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a plan View of the spool frame and spool frame casing with springs and spools in position.

Fig. 2 is a front View of Fig. 1.

Fig. 3 is a plan view of the outside casing 'of my device.

Fig. 4: is a side view of the outside casing of mydevice, showing the tension adjustment in place.-

ceiling 19; 3 are the spring spools 4 is the bolt on which the spring spools 3 operate, each sprin spool 3. having a steel spring as 5, one end thereof being fastened to the inner side of spool 3 at 6, and the other end thereof being fastened to bolt 4 at 7, as shown in Fig. 5; a metal bar 81is shown fastened in any suitable manner across the inner hollow portion 9 ofspools 3 for'lthe purpose of holding :spring 5 in place in the hollow portion 9 ofspools 3.

he outside casing of my device is shown at 10 in Figs. 3 and 4, the same beingconvex on the outside and concave on the inside and is made of metal'of having a band flange: 11 at itsupper end with an offset groove 12 cut therein, adapted to connect casing 10 with spool framel .by pin 13 fastened to casing 1, as shown in Fig.

Connected to casing 10 by rivets 14: are shown tension adjustments 15, one on each ide thereofifor the purpose of operatinga plurality of chalk holders in opposite directions, the upper portionthereof heingadjustable up and down by bolts 16. Extended wire rope 17 is shown placed .onaii incline from the ceiling, as shown in Fig. 9 in either direction and held in place by a plurality of 18 of different lengths, fasceiling 19 over the billiard tables by bolts 20, pulleys 21 are shown connected to hangers 18 over which wire rope 17 passes. On wire rope 17 is shown a stop bar 22; pull-down pulleys are shown at 23 resting on wire rope 17; attached to said pulley frames 24 is cord 25; attached to the lower end of cord 25 is chalk holder 26 by tenecl to the rings 26; these chalk holders 26 are made of metal and are positioned near the end of a plurality of billiard tables 27.

spring is shown at 28 in chalk holder 26; chalk is shown in chalk holder 26 at 29, the chalk'being held in chalk holder 26 by flange 30 and cap 31 and is fed down by spring 28, cap Ell-being machine threaded into chalk holder 26.

The operation of my chalking device for billiard tables, is as follows:

Wire rope 17 is fastened to and wound around the spring spools 3, one for each direction, as to the number of billiard tables to operate over, then wirerope 17 is drawn a the required thickness,

where the same is fastened t cha k h d?! 15, is regulated by'bolts 16 to any tension-on Wire rope l'? when corc 17 are pulled down to use l lchalkgholder 26, wire;1-ope; 17 is drawn out s 1 e from "casing :10 through tension adjustment -back into casing 1-15, .and' when released the tension adjust- I mentl5' being'so ad1usted as to return wire 5 rope 17 and, pull'down pulleys to their "Wire'ropel7 being placed on an incline from originalposit ons at the speed required;

purpose of returning thelceiling is for "the I pulleys 23 to their originalfpositio 'is near '21; chalk 2 9 is replenished in chalk pulleys holder 26 by removlng cap 31-and spring 28.

Having thus described my invention, what 'I'claim' as new and desire to secure by Letirrthe spool'frame,
